Cogo is a smart and versatile geo-data registration app. Use one super user-friendly tool for all kinds of data.


Every user can use this app anywhere, without instructions. Most of our users set-up their forms and train the staff in less than a day.


Give your users direct access to your geo-data, making collaboration, sharing realtime information and giving feedback easier.


When working offline, the data is stored locally. When working online, the data is stored directly in your own GIS environment via WFS-T.

Your data

Cogo has a unique way to collect geospatial data: your data is stored directly in your own server. This is called a decentralized approach and highlights one of its most fundamental strengths: decentralization give back ownership of data to consumers and ensures their privacy. Cogo doesn't track you nor does it save your data elswhere.

Decentralization keeps you in control of your data and opens up all kinds of new possibilities to analyse your data. At the most basic level, a decentralized approach will provide your line-of-business managers (think marketing, product, management, possibly finance) with direct, full-time access to an analytics resource, and those managers will get the quickest turnaround on their requests.

When data is centralized, it is controlled by a 3rd party organization. Cogo's decentralized approach on the other hand, is controlled by you. No other can access, sell or track your data.

How Cogo works


In the Cogo admin environment, connect to your GIS server (WFS-T) such as GeoServer. Configure the form your field workers will use and invite users.

Frequently Asked Questions.

  • The best way to determine the accuracy level to expect from a particular external GPS receiver is to check the website of the receiver's vendor for GPS specs. If you are looking for the accuracy level of an integrated GPS receiver or if you would like to compare accuracy levels of various external GPS receivers, you might find the MTDC GPS Receiver Horizontal Accuracy Reports published by the USDA Forest Service helpful. This organization has tested GPS receivers of various grades to determine their accuracy.

  • Cogo collect is available on the App Store for iPad and iPhone, the Play Store for Android devices and the Microsoft store for Windows devices. You can also use Cogo in your web browser as desktop web app.

  • GeoServer is an open source server for sharing geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. GeoServer fully supports transactions.

  • The Web Feature Service (WFS) is a standard created by the Open Geospatial Consortium (OGC) for creating, modifying and exchanging vector format geographic information on the Internet using HTTP. A WFS encodes and transfers information in Geography Markup Language (GML), a subset of XML.

    The Transaction operation can create, modify, and delete features published by a WFS. Every WFS-T transaction is atomic, meaning that if any of the elements fail, the transaction is abandoned, and the data is unaltered. A WFS server that supports transactions is sometimes known as a WFS-T server. GeoServer fully supports transactions.


Cogo is developed by Baas geo-information, a company that focuses entirely on the application of GIS for both governments and companies.
